Member Function Documentation

const PdfDict * PdfDict::dict ( ) const

virtualnoexcept

Return this object as PDF dictionary object.

Reimplemented from ipe::PdfObj.

Referenced by ipe::PdfFile::parse().

String PdfDict::dictRepr ( ) const

noexcept

Return PDF representation of the PdfDict without the stream.

void PdfDict::dictWrite ( Stream &  stream, const PdfRenumber *  renumber, bool  inflate, int  length  ) const

noexcept

void PdfDict::write ( Stream &  stream, const PdfRenumber *  renumber, bool  inflate  ) const

virtualnoexcept

Implements ipe::PdfObj.

References ipe::Buffer::size().

void PdfDict::setStream

(

const Buffer &

stream

)

Add stream data to this dictionary.

void PdfDict::add	(	String	key,
		const PdfObj *	obj
	)

Add a (key, value) pair to the dictionary.

Dictionary takes ownership of obj.

Referenced by ipe::PdfResources::collect().

const PdfObj * PdfDict::get ( String  key, const PdfFile *  file  ) const

noexcept

Look up key in dictionary.

Indirect objects (references) are looked up if file is not nullptr, and the object referred to is returned. Returns nullptr if key is not in dictionary.

bool PdfDict::getNumber ( String  key, double &  val, const PdfFile *  file  ) const

noexcept

Retrieve a single number and stor in val.

References ipe::PdfObj::number(), and ipe::PdfNumber::value().

Referenced by ipe::Latex::createLatexSource().

bool PdfDict::getNumberArray ( String  key, const PdfFile *  file, std::vector< double > &  vals  ) const

noexcept

Retrieve an array of numbers and store in vals.

Referenced by ipe::Document::formatFromFilename(), ipe::Face::glyphIndex(), and ipe::PdfWriter::~PdfWriter().

bool PdfDict::deflated ( ) const

noexcept

Is this stream compressed with flate compression?

References ipe::PdfObj::name(), and ipe::PdfName::value().

Referenced by ipe::Document::formatFromFilename(), and ipe::PdfWriter::~PdfWriter().

Buffer PdfDict::inflate ( ) const

noexcept

Return the (uncompressed) stream data.

This only handles the /Flate compression.
